Multiply polynomial $ \, \color{blue}{ -4x } \, $ by $ \, \color{orangered}{ 2x+5 }$.
Answer
$$ \color{blue}{-4x} \cdot \left( \color{orangered}{2x+5} \right) = -8x^2-20x $$
Explanation
We can use distribution property to multiply the polynomial by the monomial.
$$ \begin{aligned} \color{blue}{-4x} \cdot \left( 2x+5 \right) &= \color{blue}{-4x} \cdot 2x + \color{blue}{-4x} \cdot 5 = \\ &= -8x^2-20x \end{aligned} $$This page was created using
